This is so beautiful. space is full of things that just happen by chance and the things those happenings leave behind are almost poetic.

[@HendrikGreaves]

It's also fiction

[@alexdesmall6916]

Greaves what exactly is fiction? Enlighten us

[@r.c.1881]

@@HendrikGreaves Bruh. You can literally observe the rings with a commercially available telescope. How is this any fiction?

The only simulation that has a planet that actually spins and has a day and night rotation

[@perfectionbox]

Saturn: Hmmm something's not quite right... I feel... naked somehow. Comet: Hold on a sec.

[@derekrichardson6415]

Nice job John!

[@Sherwoody]

An interesting theory, the modelling makes it easier for non-scientists (like me) to understand. Would the object that caused the collision be similar to Phoebe? Could a sample mission possibly determine fragments of two bodies from different locations in the solar system that would confirm your idea?

[@groaningmole4338]

You have to remember we're talking about Solar System impact velocities here, which usually are on the order of tens of thousands of kilometres per hour. The impactor would probably have been vaporized completely. Most Saturn-crossers are either Centaurs or comets, so similarity to Phoebe makes sense. (BTW, I'm not the author of the talk, just to be clear.)

Cool

Its crazy how something so small yet can become something so big

Ring system

[@petterlarsson7257]

why did you use so few particles for the impact and so many for the actual rings

[@user-cm2yw9fc6v]

Moon named atlas

[@marcusarts24]

Like ring

[@codypeterson7387]

This simulation dosent entirely make sense when looking at other objects in the planetary system, where is this evidence of vast amount of cratering on some moons, primarily on one side of the moon as it moves through the particles. I would love to see a better interaction with the surrounding moons as this seems like a great idea, but only in a vacuum.

[@rochelimit55555]

Wait, I don’t think Mimas can be formed from the ring, idk

[@BloodmoonYt9]

what did u use for tihs

[@IARRCSim]

Daphnis would be another example of a reaccreting moon, right?

[@WhyIsEarthInTheFreezeZone]

What about Pan? Yes I’m serious. Saturn has a moon called Pan.

[@IARRCSim]

@@WhyIsEarthInTheFreezeZone yeah Pan is bigger than Daphnis too. Mimas is so big and spherical that I'm surprised it would have formed from the reaccreting ring material. Mimas would also need to be the youngest spherical moon in the solar system since the rings are less than a billion years old.

[@rochelimit55555]

@@IARRCSimidk I think Mimas is too spherical to be formed from a ring.

So where are the Earth's rings after the moon was made from a Mars sized planet hitting the earth?

[@polishkerbal6920]

Moon.

And some close to earth asteroids, with 2 dust clouds in the L4 and L5 points.
